/ so adjustabie that the rays from the lamp may be thrown in every possible direction.

'ihe invention -consists of a tubular section-` mounted on a suitable base and having hinged to its opposite enden extension rod provided 'at one end With a`pair of .clamps adapted to support the iarnp socket.

The invention further consists in so mounting the socket carrying rod on the tubular section that said rod may be tele scoped. into said tubular section when 'der sired.

The invention further consists in certain novel features of construction and arrangement of parts which will be 'fully understood by reference to the description of the draW- ings and to the claims hereinafter given.

For the purpose of illustrating the invention one preferred form thereoi2 is illustrated in the drawings, this'form having been found to give satisfactory and reiiable results, ai though it ,is to be understood that the various instrumentalities oi' which the invention consists can be variously arranged and organized, and that the invention is not limited tothe precise arrangement and organlzation of these instrumentaiities as herein shown and described.

Figure 1 represents. an elevation of the upper portion of a lamp support embodying the principles ot the present'invention.

Fig. 2 represents an elevation of the support with the supporting rod telescoped lnto the tubular section.

Fig.. 3 represents a Sectional detail on line 3 3 on Fig. 1, and Fig. 4 represents a seotion on line 4-i on Fig. 2.

In the drawings 10 is a ball shaped member or center-piece 'having a plurahty of 5b radiai 11 'extending therefrom and formin g a base.

'The upper part of the ball 10 is provided with a hub 12 into which is threaded the standard or tubular section 13, having a clear straight passage therethrough and the upper end of which has threaded thereto a nut 141.

Surrounding the tubular section 13 and beneath the nut 14; is a sleeve 15 provided with a laterally extending Wing or projeo tion 16, the outer end oi which has a disk-like portion 17, through the center ot which is an openin to receive the pivot bolt 18.

Stra .dling the disk portion 1'? is a bifurcated member 19 provided with dish portions, having alined openings extending therethrou -h to' receive the pivot bolt 13, one end oY which is threaded tothe hub 20 formed upon one of the disk portions of the biturcated member 1'9, While the op posite end thereof is provided with a head 21.

lt is obvious that by turning the pivot',`

bolt 18 the two disk portions ot the bifurcated member 19 may be brought .into iirm contact- With the outer faces or' the disk 17 interposed.between said disk portions and f canse sufiicient friction thereon to lock the member 19 to the sleeve 16 in adjusted position. i

The member 19 is provided with a tubular hub 22 in. which is mounted the cylindrical extension rod 23. This rod or extension 23 may be adjusted endavise in the hub 22 and ciamped in adjusted position by means of the clamp 24 threaded to the boss 25 extending from the hub 22.

lThe anis of the pivot bolt 18 is equi-distant iromthe axis of the hub 22 and the anis of the tubular section 13, so that When the bifui'cated member 19 is moved into the position indicated in Fig. Qof the drawings, the axes of the rod 0r extension 23 and the tubuilar section 13 Will be in alinement. The diameter of the rod or extension 23 is less than the interior diameter of the tubumember 27. l

section 13 ind then againbe locked in adjusted position by means otsaid clamping By loosening the clamp 24 and moving the extension rod 23 endwise through the tubulan hub 2S, said rod may be entirely removed from the tubular section 13 and then the member 19 may be moved into any the pivot bolt 18.

the extension rod 23. Threaded to the pro'- jection 29 is a ball 30 positioned between two swivel members 31 preferably made of.

Babbitt metal and having reduced ends p0- sitioned in openings 32 in the lower ends of the sockct-clamps 33. The upper ends 341 ot said socket-.clamps are curved with their inner iaces adapted to impinge upon a lamp socket 35 ot' any ,well known construction.

rlilie socket-clamps 33 are connected t0- gether by means of the clamping bolt 36,

one end oi which is provided with a slotted` head for turning said bolt, said head bear-y ing against one socket-clamp 33, while the opposite end is threaded to a nut bearing against the outer face of the other socketclamp 33 as indicated in Fig. 4 of the drawines.

when the clamping bolt 36 is adjusted, it not only clamps the socket-clamps 33 upon the socket 35, but also clamps the swivels 31 upon the ball 30,'thus positioning the socket-clamps 33 at any desired angle to the axis ot the projection 29 as, for instance, in

the positions as shown in Figs. 1 and 2 in the drawings. Y

It is obvious that by the adjustment of the clamping bolt 36, the socket 35 may be easily removed from thcsocket clamps 33 and it is also self evident that b a slight turn oi the clamping bolt 36, the 'rictionof the'svfivels 3.1 upon the ball 30 and between these ivels and the inner faces of the soclretctamps 33, may be relieved suiicie'htly to permit the socket-clamps to be movedl into a new position and locked in said adjusted position by said clamping bolt 36.

The lampssupporting-extension rod 23 may be adjusted endwise or longitudinally in the hub 22 to move the socket 35 to any desired distance 4from said hub and then said extension `rod may be clamped in adjusted positionby means of clamp 24.. The biiurcated member may be moved into any desired angle relatively to the sleeve 15 and clamped in adjusted' position by the pivot bolt 18. This whole hinged device, 15, 16, 19 may be swung about the'axis of the tubular .justa y inname section 13 and locked in adjusted position by means of the clamping member 27.

A portion of the nut 14:10u the upper end of the tubular section 13 projects into the lateral slot 37'in the ring 16 thereby preventing the sleeve 15 from being displaced from its normabposition as indicated in the drawings. Y

This makes a very desirable lamp support particularly adapted for garage work, as by means of the structure shown the various parts may be quickly adjusted so that the light may be thrown up under machines, ci' may be throwndown upon any of the working parts of the mabhine. In fact the device may be adjusted so as -to throw light wherever it may be mostneeded `One great advantage of the device is, that whenever it is found unnecessary to project the light at some distance from the vertical standard or tubular section 13, the exten- .sion rod 23 may be telescoped into the said tubular section 13 as is indicated in Fig. 2, thereby causing it' tooccupy less space.

It is believed that the operation of the` device and its many advantages will be thoroughly understood without any further description.
